High-yield vernicia fordii seedling cultivation method

Abstract

The invention discloses a high-yield vernicia fordii seedling cultivation method. The cultivation method comprises the following steps of storage: selecting seed tree seeds with high oil yield for storage; seed selection: selecting large and full seeds without mildew spots and wormholes; soaking: selecting a room, putting the seeds into warm water with the temperature of 30-40 DEG C, adding hymexazol powder into the warm water, diluting the hymexazol powder by 400-800 times, soaking for one day per day, replacing the water, putting rooting powder, soaking for one day per day again, diluting the rooting powder to one thousandth, humidifying the surfaces of seeds by a humidifier when the rooting powder is exposed at night, keeping the indoor temperature at 30-40 DEG C, and finally, selecting the seeds sinking to the water bottom; and sowing, wherein 1-2 immersed seeds are put into each bag of nutrient soil. According to the method, large and full seeds without mildew spots and wormholes are screened and soaked, so that the budding time difference of different seeds is shortened, management is convenient, the quality of vernicia fordii seedlings is effectively improved, the transplanting survival rate is high, the vernicia fordii seedlings grow fast, the oil yield is high, and the method is relatively economical.

Description

technical field [0001] The invention relates to a method for cultivating tung tree seedlings, in particular to a method for cultivating high-yield tung tree seedlings, and belongs to the technical field of tung tree cultivation. Background technique [0002] Tung (scientific name: Vernicia fordii (Hemsl.) Airy Shaw) is a deciduous tree belonging to Euphorbiaceae, up to 10 meters high; the bark is gray and nearly smooth; the branches are thick and hairless, the leaves are oval, and the top Short pointed, base truncated to shallow cordate, gray-green below, petiole nearly as long as leaves, glabrous, flowers monoecious, first leaves or open at the same time as leaves; petals white, with light red veins, dense ovary The drupe is pilose, the drupe is nearly spherical, and the pericarp is smooth; the seed coat is woody. It blooms from March to April and bears fruit from August to September. [0003] In the traditional tung tree planting, the specifications of the seeds are not ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for cultivating high-yield tung tree seedlings, to solve the above-mentioned background technology that the specifications of the seeds are not limited before planting, resulting in uneven seed quality, resulting in a large time difference in germination, which is not conducive to the seedling stage Therefore, there is a problem of poor quality in the seedling raising period, which leads to slow growth and low yield of tung tree
